Optical waveguide ends are mechanically fixedly positioned so that an end portion projects from the clamp; electrode structure is disposed in relation to that projecting end for deflecting it in one or two directions basically perpendicular to the axis of the waveguide; and a high frequency oscillation is provided to the electrodes at an amplitude such that the inhomogenic field in the vicinity of the electrode structure moves that end portion, preferably at resonance frequency, to pass through maximum optical coupling with stationary optical input or output.
